Sea fish grading screening device

Abstract

The invention provides a sea fish grading screening device, and belongs to the technical field of sea fish screening. The sea fish grading screening device comprises a fish receiving frame, two fixingplates, a grading funnel, a first fish suction mechanism, a second fish suction mechanism, a driving mechanism and a fish feeding mechanism; two partition plates are arranged in the fish receiving frame and divide the fish receiving frame into a first storage cavity, a second storage cavity and a third storage cavity, and the two fixing plates are symmetrically arranged between two support plates; the grading funnel is vertically and rotationally arranged between the two fixing plates and comprises an upper straight pipe, a conical pipe and a lower straight pipe, when the conical pipe rotates, the first fish suction mechanism can suck medium-sized fishes falling into the conical pipe into the first storage cavity, and the second fish suction mechanism can suck small fishes falling into the conical pipe into the third storage cavity; and the driving mechanism can drive the grading funnel to rotate, and the fish feeding mechanism can evenly pour the fishes into the conical pipe. According to the sea fish grading screening device, the sea fishes can be graded and screened according to the weight, operation is easy, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of marine fish screening, and relates to a marine fish grading and screening device. Background technique [0002] Sea fish on the market are sold at different prices according to their size and weight. Therefore, sea fish need to be graded and screened before sale to meet the needs of different consumers. [0003] After the sea fish is caught, the fish is manually graded and screened. The workers directly catch the fish with bare hands, then make a rough estimate of their weight, and then put them into different storage boxes. The accuracy is poor; in addition, in order to ensure that the fish The freshness of the freshness requires multiple people to concentrate on screening, the work intensity is high, and the identification ability of each person is different. In the end, there is a large deviation in the few fish selected, which requires re-screening when selling, which is time-consuming and laborious. ...
